CodeTwo Email Signatures for Office 365 is a cloud-based software that allows admins to centrally create, deploy and manage email signatures and disclaimers for all users in their Microsoft 365 organization. 

CloudM is also not bad. It’s designed as an email signature management solution that is simple to configure, works across desktop and mobile, integrates with CloudM Smart Teams. 

However, CodeTwo is the clear winner. CloudM’s only advantage is their automation via Smart Teams and its custom fields. Which makes a real difference. If you’re looking for an enterprise email signature solution, Code Two should be your 1st pick.
